The Structure of Drawings Gradient.Style = com.sun.star.awt.GradientStyle.LINEAR Gradient.StartColor = RGB(255,0,0) Gradient.EndColor = RGB(0,255,0) Gradient.StartIntensity = 150 Gradient.EndIntensity = 150 Gradient.Angle = 450 Gradient.StepCount = 100 RectangleShape.FillStyle = com.sun.star.drawing.FillStyle.GRADIENT RectangleShape.FillGradient = Gradient Page.add(RectangleShape) This example creates a linear color gradient (Style = LINEAR). The gradient starts with red (StartColor) in the top left corner, and extends at a 45 degree angle (Angle) to green (EndColor) in the bottom right corner. The color intensity of the start and end colors is 150 percent (StartIntensity and EndIntensity) which results in the colors seeming brighter than the values specified in the StartColor and EndColor properties. The color gradient is depicted using a hundred graduated individual colors (StepCount). Hatches To create a hatch fill, the FillStyle property must be set to HATCH. The program code for defining the hatch is very similar to the code for color gradients. Again an auxiliary structure, in this case com.sun.star.drawing.Hatch, is used to define the appearance of hatches. The structure for hatches has the following properties: Style (Enum) type of hatch: simple, squared, or squared with diagonals (default values in accordance with com.sun.star.awt.HatchStyle) Color (Long) color of lines Distance (Long) distance between lines in hundredths of a millimeter Angle (Short) angle of hatch in tenths of a degree The following example demonstrates the use of a hatch structure: Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Dim Hatch As New com.sun.star.drawing.Hatch Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point RectangleShape.FillStyle = com.sun.star.drawing.FillStyle.HATCH Hatch.Style = com.sun.star.drawing.HatchStyle.SINGLE Hatch.Color = RGB(64,64,64) Hatch.Distance = 20 Hatch.Angle = 450 RectangleShape.FillHatch = Hatch Page.add(RectangleShape) This code creates a simple hatch structure (HatchStyle = SINGLE) whose lines are rotated 45 degrees (Angle). 116 OpenOffice.org 3.2 BASIC Guide · March 2010
The lines are dark gray (Color) and are spaced is 0.2 millimeters (Distance) apart. Bitmaps The Structure of Drawings To use bitmap projection as a fill, you must set the FillStyle property to BITMAP. If the bitmap is already available in OpenOffice.org, you just need to specify its name in the FillBitMapName property and its display style (simple, tiled, or elongated) in the FillBitmapMode property (default values in accordance with com.sun.star.drawing.BitmapMode). If you want to use an external bitmap file, you can specify its URL in the FillBitmapURL property. The following example creates a rectangle and tiles the Sky bitmap that is available in OpenOffice.org to fill the area of the rectangle: Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point RectangleShape.FillStyle = com.sun.star.drawing.FillStyle.BITMAP RectangleShape.FillBitmapName = "Sky" RectangleShape.FillBitmapMode = com.sun.star.drawing.BitmapMode.REPEAT Page.add(RectangleShape) Transparency You can adjust the transparency of any fill that you apply. The simplest way to change the transparency of a drawing element is to use the FillTransparence property. The following example creates a red rectangle with a transparency of 50 percent. Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point RectangleShape.FillStyle = com.sun.star.drawing.FillStyle.SOLID RectangleShape.FillTransparence = 50 RectangleShape.FillColor = RGB(255,0,0) Page.add(RectangleShape) To make the fill transparent, set the FillTransparence property to 100.
